hello, If im using a 200 watts cab (8 @ ohms) into a 300 watts (300W@8ohms, 500W@4 ohms) head, it can damage the cab? and if im using 2 cabs of 200 watts (8 @ ohms) into the same head, it take out 400 (at 4@ohms) watts? is this combination will damage the 200 cabs as well? how many watts will come out from each cab? Thanks!
